Green Roof Waterproofing
Green roofs, also known as living roofs, have become increasingly popular due to their numerous benefits, including improved aesthetics, enhanced energy efficiency, and positive environmental impacts.
A key step in the successful installation of a green roof is ensuring its waterproofing. Proper green roof waterproofing is essential to protect the building structure from potential water damage and ensure the longevity of the green roof.
Maximum Green Roof Protection
Green Roof Waterproofing
Waterproofing a green roof starts with choosing the right materials. High-performance liquid membranes, such as LOTUS, are commonly used due to their excellent adhesive properties, seamless coverage, and long-lasting waterproofing capabilities.
The product effectively adheres to all substrates, creating a robust and durable layer of protection against water infiltration. Moreover, LOTUS, high-performance waterproofing solution is cold-applied and cold-cured, which makes their application user-friendly and efficient.
Green Roof Installation
Following the waterproofing stage, the green roof installation process begins. This typically includes installing a root barrier over the waterproof membrane, laying a drainage layer, and then adding the growing medium and the plants. The choice of plants depends on several factors including local climate, roof load capacity, and the desired level of maintenance.
Ongoing maintenance and regular inspections are crucial to the longevity of a green roof. This includes ensuring the waterproofing membrane remains intact and efficient, and the vegetation is healthy and thriving.
Green Roof Repair and Restoration
Green roofs can help to reduce stormwater runoff, improve air quality, and provide a habitat for wildlife but like any roof, green roofs can experience wear and tear over time. If your green roof has water damage, it's important to have it repaired as soon as possible to prevent further damage. The longer you wait, the more damage the problem is likely to cause.
There are a number of things that can damage a green roof, including:
Weeds and Pests
Weeds and pests can quickly take over a green roof if they're not controlled. This can not only make your roof look unsightly, but it can also damage the plants and the underlying waterproofing membrane.
Wind Damage
Strong winds can uproot plants and damage the substrate. This can expose the waterproofing membrane to the elements, leading to leaks.
Water Damage
If your green roof leaks, it can cause significant damage to your home or business. Water can seep through the plants and the substrate, damaging the waterproofing membrane and the underlying roof deck.
Animal Damage
Animals, such as raccoons and squirrels, can damage green roofs by digging up plants and eating the substrate.
How to Repair Green Roof Water Issues
Repairing the waterproofing issues of a green roof requires a careful approach, as you are dealing with both living plants and a complex roofing system. Depend on the extend of the damage, we will either repair or replace the substrate, or even the entire waterproofing membrane.
» Identify the Problem
The first step is to identify where the water is infiltrating. This may involve looking for visible signs of leaks inside the building, or you might need to inspect the drainage of the green roof to locate areas where water is not flowing properly.
» Remove the Overburden
Once the problem area has been identified, we carefully remove the green roof "overburden" in that area. This includes the layers of plants, growing medium, filter fabric, and drainage layers. We keep the removed materials in a safe place, ensuring the plants are watered and protected from drying out.
» Inspect the Layers
After exposed the waterproofing membrane, we look for visible signs of damage such as holes, cracks, or blisters. We also inspect the seams to make sure they are still intact.
» Repair The Membrane
If we find a small hole or crack, we repair it with a patch of the waterproofing membrane. We ensure to use a high-performance liquid membrane, such as LOTUS, which offers excellent adhesive properties. We clean the area around the damage thoroughly, apply the membrane material, and then secure the patch.
» Test The Repair
Before replacing the overburden, it's important to test the repair. This may involve flooding the area with water and checking for leaks. We allow the area to dry before moving onto the next step.
» Replace The Overburden
Once we're confident the waterproofing membrane has been successfully repaired, we replace the drainage layer, filter fabric, growing medium, and plants. It's important to replace these layers in the correct order and to the right depth.
