Claysolve Hydrorock

Sustainable drainage solutions for clay soil

Effective infiltration for clay

Hydrorock-filled boreholes for onsite clay soil infiltration

Unitary aquifer creation

Connecting Hydrorock to the permeable layer forms a large, unified natural aquifer

Optimises land use

Modules of varied shapes and sizes can be dispersed across a site to suit its requirements and improve land use

Increased capacity

Blocks can be easily added above a bore hole to increase buffering capacity

ClaySolve by Hydrorock and BluWater Solutions UK

Hydrorock blocks offer sustainable drainage for clay soils.

Boreholes filled with Hydrorock quickly channel surface water down to the permeable soil below.

Long-term effectiveness with minimal maintenance

Design detailing

Work with nature to unlock SuDS on clay soil

The ClaySolve system uses Hydrorock-filled boreholes through clay to channel surface water into the permeable layer below, forming a large natural aquifer from surface to depth.

Extra buffering can be added with Hydrorock BD or HD blocks installed in a trench above the boreholes.

Enables land use and increased construction

Hydrorock systems are solid, geotextile-wrapped blocks that can be positioned right next to buildings – avoiding the large exclusion zones needed for big, centralised sumps.

ClaySolve’s efficiency and Hydrorock’s modular design allow small infiltration systems to be spread across a site, helping developers optimise land use.

System design depends on project factors such as water volume, soil type, clay thickness, permeability and site layout.
Test drilling is recommended to confirm depth and thickness of the permeable layer.
Larger systems may need air vents for faster water inflow.
Looped inflow systems can be used for quicker inflow and cleansing if filters are blocked.
All systems should include a filtered inlet, available in three sizes depending on volume.

Installation

Trench excavation requirement, minimum 1m (W) x 1.3m (D) x 5m (L).
A 325mm diameter borehole should be drilled in the middle of the trench through the clay layer and at least one 1m into the permeable layer.
The borehole should be filled with Hydrorock IR40 blocks (100cm (L) x 20cm (W) x 20cm (H)) stacked tightly and vertically end-to-end.
Total number of boreholes required will depend on system capacity and the infiltration rate of permeable substrate.
The bottom Hydrorock block should touch the bottom of the borehole and the top block should protrude 50 mm above the top of the hole at the bottom of the trench.
The bottom of the trench should be filled with a levelled sand layer 100mm thick.
Hydrorock BD440 blocks (120cm (L) x 100cm (H) x 40cm (W)) should be placed into the trench on the sand, stacked tightly together in pairs and abutted end-to-end.
Other blocks from the Hydrorock range with varying sizes and densities may be specified according to system capacity requirements and above surface weight loading.
