Tenerife, Canary Islands, Spain

Description:
The building foundation is 1.2m under the sea level and the distance from the ocean approximately 200m, one of the few basements in this area of Puerto de la Cruz due to constant water ingress. Despite continuous pumping, the excavation area constantly had 5 – 10 cm of water. During high tide, the water level rose significantly and the pumps had to be turned off at night due to noise pollution, repeatedly flooding the base slab with water.

Products Used:
PENETRON ADMIX was dosed for the base slab, exterior walls and pillars. The cold joints were simply treated with a coat of PENETRON slurry; no other joint waterproofing material was applied. This was enough to completely waterproof the joints. Hairline cracks were treated with PENETRON. Four days later, all water leakage through these cracks stopped and white crystal growth could be seen on the surface.
