Biaxial Geogrid

Wrekin geogrids are advanced geosynthetic materials with a competitive range of engineering properties including strength, modulus, weathering resistance corrosion, resistance and creep performance that are the equal of any others in the world. Our E-Grid range of biaxial geogrids are manufactured from polypropylene which is unaffected by all chemicals, including acids, alkalis, salts & micro-organisms normally found in soil.

Biaxial Egrids can solve pavement problems by reinforcing granular sub-bases, capping layers & railway ballasts in areas of weak/variable soils. When granular particles are compacted over these grids, they partially penetrate and project through the apertures to create a strong and positive interlock.

The health, safety and wellbeing of our colleagues, customers and communities has been our priority since the outbreak of the Covid-19 virus. We have closely followed the advice of our Government and have implemented appropriate actions to help prevent the spread of the virus in our branches.

Following last night's announcement from the Prime Minister we believe the responsible approach is to suspend trading for the next three weeks in all our branches. With immediate effect all PDM Buildbase, Hirebase and Electricbase branches will be closed for deliveries, collections and online orders. Subject to receiving clarification from Government, we aim to continue with the supply of materials through a small number of branches to support essential repair and maintenance activity.

The situation is unpredictable and these measures have not been taken lightly. We apologise for the inconvenience caused during this period, but we will take all measures we can to support the Government in their efforts to control the spread of this virus.

We will keep you updated on further developments and will announce when branches are ready to reopen.

Due to the above, we would much prefer for all payments to be made either electronically or via the telephone.

To this end and to assist with payments we have the following options;

  • Our credit teams are available to take your calls from 7.30am until 5.00 pm Monday to Friday and 8am to 12 noon on a Saturday.
  • We will be waiving all credit / business card payment fees until the end of April, so why not give us a ring and pay your account securely by card.
  • Our credit office telephone number is 0141 892 8960
  • Our bank details for electronic transfers are located on our payment 'remittance advice' area of your statement
  • Rather than post us your remittance advice we would prefer these to be emailed to us at [email protected]

Thanks for your understanding. Stay safe
