Green Roofs & Walls - Garden

About Us

To make green roofs and living walls reliable building components that cool cities, absorb stormwater and improve daily life for the people who live and work beneath them.

Who We Are

About Our Company

Dolmans Landscaping Group B.V. designs and builds living architecture: extensive and intensive green roofs, rooftop terraces, vertical gardens and green facade systems for commercial, institutional and residential buildings. Our projects begin where the building ends, with structural capacity, roof membrane type, drainage paths, wind exposure and access for maintenance all reviewed before a plant is specified. We work closely with architects, roofing contractors and engineers to deliver assemblies that are protected from root penetration and water ponding, and we install growing media and plant material suited to the shallow, exposed and often harsh environment of an urban rooftop.

Operating in Bunde and the surrounding region, Dolmans Landscaping Group B.V. treats a green roof as a long-term building system, not a decorative extra. We offer establishment care and ongoing maintenance because plants on a roof depend on consistent attention, particularly in the first two growing seasons. Our team includes horticulturists, irrigation technicians and installers trained in fall protection, and we document each project with as-built layer details, plant lists and maintenance manuals that building owners and facility teams can use for years.

  • Documentation is retained for the full period the contract and statute require.
  • Public separation and traffic management are planned before equipment arrives.
  • Nonconformities are logged, corrected and closed with evidence.
  • Subcontractors are audited against the same standards as our own crews.
  • Waste streams are segregated and documented to the point of final disposal.

Our Mission

To make green roofs and living walls reliable building components that cool cities, absorb stormwater and improve daily life for the people who live and work beneath them.

Our Advantages

Why Clients Choose Us

Climate-Matched Plant Palettes

Species are selected for exposure, root depth and local weather rather than catalog appeal. Plants that suit the conditions need less intervention and recover better from stress.

Care Beyond Installation

Establishment and ongoing service keep living systems healthy, protecting your investment during the vulnerable first seasons and well beyond.

Warranty-Conscious Installation

We coordinate with membrane suppliers and roofing contractors so green roof work complies with warranty conditions and protects the waterproofing underneath.

Rooftop Safety Practices

Crews use fall protection, controlled material hoisting and clearly marked work zones. Safe execution is essential when working at height on active buildings.

Structure-First Engineering

Load capacity, wind uplift, parapet height and access are verified before design is finalized. A beautiful roof means nothing if it overloads the deck or compromises safety.

Performance Documentation

As-built layer drawings, plant lists and maintenance manuals are delivered at turnover. Documentation helps facility teams and supports sustainability certification submissions.

Honest Schedules

We publish calendars we can actually keep and tell you early when something slips, because a late warning costs you more than a missed day.

Equipment We Own

Our fleet and tooling are maintained in-house, so peak-season schedules are not hostage to rental availability or third-party breakdowns.

Clean Handover

Sites are left in a condition you would accept without being asked, and punch lists are closed before we ask for acceptance.

Considering A Green Roof Or Living Wall?

Send Dolmans Landscaping Group B.V. your building drawings and goals. We will review feasibility, outline suitable systems and explain the structural and waterproofing steps involved.

Green Roofs & Walls - Facade Cleaning

Services

Every system is coordinated with the structural engineer and roofing contractor, from load calculations and waterproofing protection to drainage layers and wind uplift, so green roofs perform without risking the building.

Our Services

What We Do

Irrigation & Drainage Engineering
Step 01

Irrigation & Drainage Engineering

Drip and subsurface irrigation for roofs and walls, with controllers, moisture sensors, filtration and freeze protection where required. Drain outlets, overflow paths and inspection chambers are designed to remain accessible, preventing the ponding and clogged scuppers that cause so many rooftop failures.

Request a Quote
Living Wall & Green Facade Systems
Step 02

Living Wall & Green Facade Systems

Modular panel walls, felt pocket systems and trellis-supported climbing plants for interior and exterior surfaces. We specify attachment methods that protect the wall, integrate irrigation and drainage, choose plants for light and wind conditions, and plan access so panels can be serviced or replaced when needed.

Request a Quote
Green Roof & Wall Maintenance
Step 03

Green Roof & Wall Maintenance

Seasonal programs including weeding, plant replacement, fertilization, irrigation checks, drain inspection and media top-ups. Visits are coordinated with building management and roof access rules, and written reports track plant coverage, drainage condition and any items requiring attention from the roofing contractor.

Request a Quote
Plant Selection & Biodiversity Design
Step 04

Plant Selection & Biodiversity Design

Planting plans using regionally suited species that handle wind, reflected heat and shallow soil, often blending sedums with native perennials and grasses to support pollinators. Plans consider bloom sequence, winter structure, fire safety setbacks and maintenance level so the roof looks intentional in every season.

Request a Quote
Intensive Roof Gardens & Terraces
Step 05

Intensive Roof Gardens & Terraces

Deeper-media rooftop gardens that support perennials, shrubs, small trees, lawn areas and even urban agriculture. We coordinate with structural engineers on loading, design irrigation and drainage for deeper soil volumes, and integrate pavers, seating, planters and lighting to create amenity space tenants will actually use.

Request a Quote
Stormwater Management Roofs
Step 06

Stormwater Management Roofs

Blue-green roof assemblies that detain and slow rainfall, helping projects meet stormwater requirements. We work with civil designers on retention volumes, flow control devices and outlet design, and document performance data that supports permitting and sustainability certification credits.

Request a Quote
Waterproofing Coordination & Root Protection
Step 07

Waterproofing Coordination & Root Protection

Protection of the building envelope under and around planted assemblies. We coordinate with the membrane manufacturer on warranty requirements, install root barriers and protection layers, and recommend flood testing or electronic leak detection before planting so leaks can be located easily, rather than after the garden is covered.

Request a Quote
Extensive Green Roof Systems
Step 08

Extensive Green Roof Systems

Lightweight, low-maintenance roof assemblies using shallow engineered growing media and drought-tolerant plants such as sedums, herbs and native grasses. Layers include root barrier, protection mat, drainage and retention board, filter fabric and media. Extensive roofs add insulation, reduce stormwater runoff and extend membrane life, with minimal added structural load.

Our Process

How We Work

  1. 1

    Feasibility & Structural Review

    We review drawings, roof type, load capacity, drainage, access and local requirements with your design team to determine which green roof or wall system is realistic for the building.

  2. 2

    System Design & Plant Selection

    You receive layered assembly details, irrigation layouts and a plant palette suited to exposure and maintenance goals, coordinated with the roofer and structural engineer.

  3. 3

    Installation & Leak Verification

    Crews install protection, drainage, media and plants in careful sequence, with leak testing completed before planting. Hoisting and access are managed to keep the building safe and operating.

  4. 4

    Establishment & Ongoing Care

    Frequent early visits help plants root in. Afterwards, scheduled maintenance protects coverage, drainage and appearance, with reports provided to the building owner each season.

It depends on structural capacity, roof type and condition. A saturated extensive roof can add many pounds per square foot, so a structural engineer must verify the deck. Older membranes may need replacement first. We review drawings and conditions and tell you plainly what is feasible.

Extensive roofs are low-maintenance but not no-maintenance. Expect several visits per year for weeding, inspection and drain checks, with more frequent care during establishment. Intensive roof gardens need more attention, similar to a ground-level garden with deeper soil and more complex irrigation.

Often. Green roofs retain and slow rainfall, reducing peak runoff, and many jurisdictions give credit for that performance. We provide layer details and retention data that your civil engineer can use when preparing permit documents and sustainability submissions.

A properly installed green roof does not cause leaks, and it can protect the membrane from sun and temperature swings. The key is quality waterproofing, root protection and leak testing before planting, along with open drains so water never ponds on the roof surface.

Extensive roofs use shallow media and tough plants, are lighter and require little care. Intensive roofs use deeper soil and support larger plants and gathering spaces, but they weigh more and need irrigation and regular maintenance. Many projects blend both on different portions of one roof.

Yes, with different design requirements. Indoor walls need adequate light, humidity control and sealed water management, while outdoor walls must tolerate wind, sun, temperature extremes and freezing. We choose systems and plants specific to each location and plan service access for both.
