Wallbarn supplies a range of outlets and drain connectotrs to help ensure the waterproofing integrity of the roof deck is maintained around the drain holes and into the rainwater outlet pipe.

Junctions and patches

Wallbarn supplies a range of acute and obtuse angles manufactured from TPE, compatible with bituminous waterproofing membranes. They are fitted into difficult areas where often a liquid waterproofing membrane can either struggle to bond to a very sharp corner, or on an outer corner can be “scalped” as it is applied, leading to a much thinner layer than the rest of the area.

These areas of the concrete deck are often the most vulnerable to leakage, so extra protection and strength across such details by a flexible, durable “patch” can help maintain the integrity of the waterproof seal.

The area should be waterproofed beneath, and then the patch is placed above it whist still tacky. Applicators should then waterproof over the whole area, so the patch is bonded above and below to the waterproofing membrane, ensuring a tough, flexible seal around the corner, joint or edge.

Patches In TPE
Wallbarn supplies a range of acute and obtuse angles manufactured from TPE that can be fitted into difficult areas as an additional protection.These are designed to be sandwiched between two layers of bituminous membrane.

Often a liquid waterproofing membrane can either struggle to bond to a very sharp corner, or on an outer corner can be “scalped” as it is applied, leading to a much thinner layer than the rest of the area.

These areas of the concrete deck can be the most vulnerable to leakage, so extra protection and strength across such details by a flexible, durable “patch”, which will adhere to the liquid waterproofing membrane, can improve the integrity of the waterproof seal.

Patches in PVC
The same types of junctions and shapes for bituminous membranes are manufactured in PVC for synthetic membranes

Wallbarn supplies the same type of reinforcement patches in PVC, for use with compatible synthetic sheet membranes.

Although most PVC membranes are manufactured in standard sheet form to a uniform shape, they may also require an additional layer around awkward details and areas which are likely to get scuffed or stretched.

These areas of the concrete deck can be the most vulnerable to leakage, so extra protection and strength across such details by a flexible, durable “patch”, which will adhere to the liquid waterproofing membrane, can improve the integrity of the waterproof seal.

In addition to the acute and obtuse angles, we also have on offer a “star-shaped” piece which can be manipulated in a large number of different shapes, ideal for very tricky corners and angles.
