North Woodside Pool

Date - 2012
Scope of Works - North Woodside Baths in Glasgow were built in the 19th Century and had been lying empty for several years due to excessive escape of water from the pool.
  • Glasgow City Council employed Waterproofing Ltd to carry out a survey to establish the structural condition of the pool and reasons for water loss.
  • The pool was of a peculiar construction with rounded stops with columns at the shallow end and three circular recesses at the deep end.

  • The perimeter screed had formed the upper 75mm of wall creating a crack and line of egress.

  • Once renders were suitably cured, 2 lines of hydrophilic strips were applied either side of the epoxy secured starter bars fixed through our renders.

  • Glasgow City engineers wanted to reduce the depth of the pool plus then felt an increased screed depth was required.

  • Reinforcement was installed in hit or miss panels

  • A waterproof concrete base was applied in hit and miss rails to allow the application of a hydrophilic strip to be fixed between panels should shrinkage occur.

  • Box outs were formed in the new concrete to create access points and sealed again with hydrophilic strips.
