The Solution

Waterproofing Hotel Football was a highly complex waterproofing project. Due to the sloped ground, this slab is at four levels with steps along.

There is a retaining wall comprising pile, capping beam, multi level slabs, upstands and blockwork off either slab or upstand. The upstands are all kickerless, therefore there are multiple construction joints and also pipe penetrations.

Trace applied 101F/Angle Joint tape reinforcement along construction joints in the same plane and 107 construction joint fillet details at horizontal and vertical changes of direction and entire 101F membrane from underside of cavity tray to 500mm down the outer face down past the capping beam/slab construction joint.

Newton 104 Crystalline Waterproofing was applied to the concrete structure to provide primary resistance to the penetration of water.

Other structural waterproofing materials used:

 – 306 Swell Mastic with the waterbar.
 – Newton 403 Hydrobond below ground around 4No lift pits, one being a double lift.
 – 309 Contact Adhesive sealing the Hydrobond bottom side around to the pile caps under the lift pits.
 – 207 DeckDrain externally over the pile cap face/slab top along the canal side and externally on the capping beam and slab face/slab top all around at the upper ground floor.
 – Flexproof-XI to seal vertical gaps between below cavity tray blockwork and structural columns.
