Moisture is a common problem for concrete block foundations – the
moisture in the surrounding soil can cause concrete erosion and hydrostatic pressure, which can push against the foundations, causing the concrete blocks to crack. For this application, a suitable waterproof membrane was needed to protect the concrete blocks from Hydrostatic pressure, water-ingress and ground movements that deforms the structure due to temperature differences over time.
LINE-X Polyureas are utilised for heavy-duty waterproofing membranes for construction projects. In this instance, XS-101 was selected because of its exceptional Water Vapour Permeability results, its elasticity and CE certified status. Before the LINE-X application, all dust and debris were removed from the area using an industrial vacuum. All holes were filled with a fast-setting adhesive. Masking tape was applied in the areas were LINE-X needed to finish, followed by a specialist wire-trim tape which allows applicators to achieve a straight edge. Without using the masking tape, the wire-trim would not adhere to the concrete blocks. Once the area was masked, a LINE-X approved concrete primer was applied to the surface. Once dry, LINE-X XS-101 was applied 2-3mm thick. After the spraying was complete, a holiday detector was used to verify the membrane was free from pinholes.
The completed application provided a durable waterproof membrane which could resist Hydrostatic pressure, water-ingress and damage caused by the ground movements. LINE-X Polyurea is being requested for construction waterproofing projects due to its quick-dry times, fast return to service and longevity of the waterproofing application.
