Water Ingress Control to Protect an Underground Gymnasium Project Case Study
Control of water ingress through external facade using resin injection.
A persistent water ingress problem occurred along the front façade, resulting in rainwater flowing into an underground gymnasium, causing damage to fixtures and fittings. Several attempts had been made to rectify the problem, which had existed for several years. Attempted repairs had included taking up the existing paving and relaying waterproof membranes to the surrounding concrete slabs, however the ingress problem still remained.
H2OX engineers put forward a polyurethane resin injection system to rectify the problem. Water was poured over the paving to activate the leaks in the gymnasium. Water ingress subsequently occurred through joints between structural steel members and the concrete soffit in the gymnasium. H2OX technicians were then able to target these areas with a systematic pattern of resin injection.
H2OX successfully sealed all the leaks in less than a week.
