Fawkon Walk, Hoddesdon

This mixed used development used Xypex Admix as well as Xypex Concentrate in the whole of the basement car park. This included Xypex Admix C1000NF being added to the concrete piled wall to create a complete waterproof barrier prior to the soil being excavated as the original decision was not to erect a liner wall against the piles but to leave the piles ‘fair face’. The slab was poured using Xypex Admix C1000NF and was jointed into the piled wall.

The decision to leave the piles ‘fair face’ meant that the male and female piles needed to be totally watertight; therefore Xypex admixture was chosen as the solution because of Xypex’s unique ability to grow Crystals.

When added to the concrete the Xypex solution gave a totally dry basement against 2 metres of hydrostatic pressure.

Xypex was also used as a remedial product to repair leaks in cracked concrete that had developed under the external walkway between the flats. The Xypex standard Crack/Joint Repair was used for this.
