Utility Pits and Penetrations

Most penetrations in pavements do not match the shape or squareness of the perspective-laying pattern.

From both serviceability and appearance perspectives, this space can benefit from being infilled with the same type of paver being used in the main mass of the paving body, or it can be infilled with a purpose designed infill unit. (Ask about UrbanStone's special infill product capabilities).

1. Compaction against drainage pits or manholes is always difficult. Thus it is recommended that the base material around these difficult areas be stabilised with 3% cement to a depth of 100mm below the finished basecourse levels, and to a width of 1 metre from the drainage outlet edge.

2. The orientation of the pit or cover is visually important. Ensure that the outside dimensions of the surround are square or rectangular, and make a smooth connection with the laying bond and pattern of the segmental paving.

3. The levels of the pit-covers should be adjusted before paving around them. It is important that water drains away from pits with lids and into surface inlet drainage structures.
