How to waterproof a concrete panel swimming pool using Maxjoint Elastic and Maxseal Flex

Drizoro – waterproofing swimming pool built with concrete panels.

The sequence of how to waterproof a concrete panel swimming pool constructed from precast panels is:-

  1. Since the floor slab is a floating slab, to account for shearing movement, it is critical to install a control joint at the wall-floating floor intersection, in accordance with 26.28aSpecs21 – Joint Sealing.
  2. See 5 Step Process Swimming Pool Protrusions video:-
  3. Vertical joints between each panel are sealed as a control joint set out in the same Spec:- 26.28aSpecs21 – Joint Sealing.
    These joints are to be 10mm(min) – 30mm(max) wide, while the depth must not be less than 50% of the width with a minimum of 10mm deep
  4. Apply Maxseal flex as per 26.06Specs21 – External-internal walls incorporating Maxmesh between coats at all joints. See the video:- above
  5. Once waterproofed we recommend a final finish of Concreseal Plastering M, a flexible waterproof (i.e. fully submersible) cement render.
