Help with our Brook project

A major project we have on at the moment is to pipe the brook running through one of our fields, the water that runs through there comes directly off of the main Hollywood by-pass and therefore carries diesel, oil and more dangerous than that: rock salt at this time of the year. So piping the brook will not only safeguard whatever rescue animals we house in that field, it will give us more grazing ground. We already have the perforated pipes to do the job but we need hardcore to put either side and on top of the pipe to allow surface water to filter through. It can be anything from road planings to house bricks. We have 80 metres to pipe so will need a large amount of hardcore.
So keep your ears open! 
Please ring the business line on 01564 823244 if you think you can help.

All the best,

Ray
