Sealing a Swimming Pool Tom Vandevenne Graco Distribution BV – Maasmechelen, Belgium tom.vandevenne@graco.com
A Graco proportioner and Fusion PC spray guns were essential tools to seal a leaking swimming pool in the Polish town of Wisła.
T
he owner of the Start Sports Center on Olimpijska 1 in Wisła, Poland was facing a number of challenges with its swimming
pool that needed to be urgently addressed. The 49x13 m swimming pool is located on the old riverbed of the Vistula. Over the years, rainwater and groundwater have had a negative impact on the reinforced concrete basin of the pool, leading to numerous cracks in its base and sides, which started leaking. The solution wasn’t as straightforward as simply draining the pool and relining it. The geometry of the pool is complicated. From the shallow end, the pool’s depth gradually increases from 1.2 meters to 1.8 meters, before plunging into a deep 4-meter section with steeply sloping walls. It is this deep part of the swimming pool where most of the cracks were occurring.
Calling in expert help Local contractor Stanepoxyd visited the site. Stanepoxyd specializes in waterproofing buildings such as wastewater treatment plants, power plants, tanks and bridges. This refers to both keeping water out, as well as keeping it in. More relevant, over the years the company has built up considerable experience in repairing leaking swimming pools of all sizes, from small private pools to large municipal pools. After carefully examining the pool and the cracks, they proposed to repair the concrete structure and spray a polyurea membrane over the whole of the pool, followed by a polyaspartic top coat. A polyaspartic coating offers specific advantages over epoxy and polyurethane coatings. It is highly flexible, as opposed to epoxies which are stiff and prone to scratches and abrasions during intense use. It also exhibits good UV resistance.
