25m² Black X-Grid® Access Route – King’s College School

This case study comes from Miguel, the Head Caretaker at King's College School. Between their Rugby and Football pitches, there was a patch of grass used as a pedestrian path and grounds machinery access route that frequently became very muddy. Miguel wanted a solution to his mud pit issue so began researching to find a product to fix his issue.

Project

Miguel began researching online to find an easy to install and permeable paving solution, which is when he came across our website and our X-Grid® (Permeable Paving Grid). He began to read the benefits that our grid carried such as: being lightweight, easy to install, strong (hold up to 420 tonnes per sqm), durable, SuDS Complaint, UV & weather resistant and made from 100% recycled plastic.

Miguel ordered 25m² of X-Grid® along with Lawn Edging the same day and received his items 3 working days later via pallet delivery.

Ground Preparation

Once Miguel received his X-Grid® he could begin creating a solid sub-base on which the grid would be installed.

He began his installation by measuring out the 25m² area and marking it in the grass before removing all of the existing turf and soil in that area down to a depth of around 70mm. From here Miguel compacted the remaining area before laying a sheet of membrane.

Membrane is used to allow rain and excess water to drain away naturally whilst acting as a shield to stop and weeds or plants from growing up and through the X-Grid® and gravel.

On top of the installed membrane, Miguel laid a 20mm layer of sharp sand to create a solid and still permeable sub-base on which the X-Grid® would be installed.

Installing X-Grid®

With the sharp sand base level, Miguel began to lay the X-Grid®. As his grid was delivered by pallet, the grid arrives in squares of 9 panels (1m²).  He started in one corner and laid one section at a time simply connecting each neighbouring section together using the specially designed slot and peg system. Laying the full area took far less time than installing concrete would have. 

With the X-Grid® in place and secure, Miguel back filled the entire area with 20mm gravel.

We estimate that around 8kg of gravel is required to fill each individual panel (330x330x40mm) so for 25m² around 1,800kg of gravel was required.

Finally, once the area was over filled with gravel, Miguel then compacted the entire area using a machine plate to ensure the surface was solid and level.

Conclusion

A huge thank you to Miguel for using our X-Grid® to solve his access route issue and then for sharing the photos and information of his installation with us to allow us to create this case study.

Miguel told us: "We have a large amount of pedestrian use which would before, turn this area into a mud pit and we had to constantly apply sand to improve it. However it was a waste of time, effort and most importantly money.

Since the X-Grid® had been installed, I can say it has improved this area 100% and to the point that I am now considering doing other sections of the grounds the same."
