Coach Park Housing Development is a residential development located in the northwest of Gibraltar. The Government of Gibraltar hired Casais Gibraltar Ltd for the construction of this Project consisting of six apartment blocks of between five and eight floors.
Casais, connoisseur of our specialization in Sika systems subcontracts us for the waterproofing of the podium and balconies. The podium works as a parking deck of the urbanization, it contains landscaped and recreational areas, covering all areas outdoor commons. In total 9,792 m2.
An adhered system is required that in case of breakage prevents uncontrolled migration of water between the slab and the waterproofing sheet.
We install a system from Sarnafil TG 76-12 Felt sheet, especially suitable for roofs inverted. It is made with flexible polyolefin, very durable, and as its plasticizers, they do not migrate. It incorporates a fiberglass mesh that gives it great dimensional stability and it adds a geotextile as well that facilitates its adhered installation. Due to the great extent of podium, the waterproofing was done by sealed compartments of 20×20 m2 separated by division joints. In each compartment, a tightness test was made by flood for 72 hours.
