A cavity drainage system is an effective way to manage water once it has penetrated the structure of your property. Simple to install, the system uses its high-density polyethylene membrane to redirect and drain water away from your home, leaving your walls and floors completely dry.

As a versatile way to manage water, a cavity drainage system is used to protect all types of structures including walls, floors, basements, refurbished areas and more. If you’d like to find out how a cavity drainage system can keep your property dry, get in touch with our specialists today.

Cavity drainage systems with Insitu

A cavity drainage system is often necessary for structures built in areas with a high water table where external walls exert pressure from built-up groundwater. In these situations, it’s unlikely standard surface treatments will stop water penetration, meaning a drainage system is the only viable solution to keep your property dry.

If you’re experiencing damp within an underground structure, such as a basement, a cavity drainage system can also be fitted with a sump pump to drain and remove water from your property. If you’d like to further explore your options, book a site survey with us today.

Penetrating Damp Remedies

Penetrating damp occurs when water infiltrates your property through external defects or internal issues, resulting in damage to your walls, ceilings, and furnishings. To effectively combat penetrating damp, it’s crucial to identify the source of water ingress and implement appropriate repairs. Our qualified damp proofing surveyor can assess your property to determine the cause of the dampness and the extent of required repairs.

Once the source of the dampness is identified, our damp proofing specialists will remove the affected material and apply a physical waterproofing membrane to expedite the drying process. Furthermore, external issues must be addressed, which may involve coating the exterior wall with a chemical water repellent to ensure water remains outside your property, protecting your living space from further damage. Prompt and effective management of penetrating damp is instrumental in preserving your home’s structural integrity and comfort.

Cavity drainage systems FAQ's

What is a cavity drainage system?

A cavity drainage system is an effective water management treatment that redirects and removes penetrating water from your property. By removing water, the system relieves pressure from your walls, creating a dry and habitable living space.

Cavity drainage systems have many benefits, including:
• Creating a dry living space
• Tolerating extreme temperatures
• Acting as a vapour barrier
• Salt and contaminant resistant
• Accommodating minor structural movement

Where a tanking membrane or coating acts to prevent water from entering your building, a cavity drainage system redirects and removes water once it has penetrated the walls. In areas with a high water table, a cavity drainage system is often more effective.
Although a cavity drainage system might not be the cheapest treatment for damp, it’s certainly one of the most effective. Costs will vary depending on the size, scale and severity of water ingress within your property.
