The Round Tower (dating back to the 1400’s) is a fortification at the entrance to Portsmouth harbour. A Grade I listed building that sits (actually overhangs) the Portsmouth sea front and is susceptible to all types of coastal weather.

The current waterproofing system, that is essential for protecting this historic tower, needed replacing with a longer term solution. The IKO Permaphalt System was chosen for this project due to the 20 year guarantee offered and the previous heritage projects IKO have successfully helped preserve with various waterproof solutions.

The existing coverings were removed and replaced by Southern Flat Roofing & Pitched Roofing Ltd, providing a surface that would withstand constant foot traffic as well as the weather that many seafront structures suffer from.
