Terram Groundsure Build Pack 4.50m x 11.1m

Availability: In stock

£33.00

Quick Overview

Ground stabilisation using Terram Build A or Terram GroundSure is one of the toughest and most durable non-woven geotextile fabrics, designed to separate and stabilise construction layers while allowing water through. It is unaffected by cement, lime, and alkaline soils making it ideal for use as a stabilisation and weed control material under driveways, access roads, patios, decked areas and paths.
From 1st October 2008 new planning rules apply for householders wanting to lay paving in their front gardens. Planning permission is now required for any impermeable surface exceeding 5m2 in a front garden.
Using a permeable landscape geotextile fabric such as Terram Build A or Terram GroundSure, in conjunction with a permeable paving solution such as gravel, permeable concrete block paving or porous asphalt, planning permission will not be required.

Terram Groundsure Build Pack 110gsm

The same material as used by civil engineers in major construction projects when building roads, foundations and installing drainage systems is available in economic
50 square metre packs for smaller projects.

A detailed installation guide is available to cover various ground conditions and wheel loading.

What is FLP Builder?

FLP Builder is a tough synthetic nonwoven fabric produced from polyethylene/
polypropylene filaments – durable, permeable and ideal for many construction applications. Normally supplied in rolls, 100M x 4.5M, the FLP Builder
contains an area 11.1M x 4.5M – easy to cut and join.

Where can FLP Builder be used?

For access areas, drives and paths, terraces and other paved areas, farm roads and gateways, for temporary working areas and material storage sites – anywhere that has to support frequent comings and goings. FLP Builder is used to separate, preventing stone from being pushed into soft ground or losing bedding sand into a stone foundation. By maintaining this separation there is no loss of stability and subsequent rutting or unevenness.

For ground drains and soakaways FLP Builder is used as a filter; stopping soil or sand clogging up drainage stone. Simply line the trench or soakaway with FLP Builder and fill with coarse stone – no need for graded material!

In both applications FLP Builder is easy to install and yields savings over conventional methods in terms of material and maintenance.


How To Use FLP Builder

For Separation:

1. Selecting the aggregate

This can comprise crushed stone, chippings, pebbles, gravel etc – containing a mix of angular large to small materials which can be well compacted to provide a stable surface.
The maximum stone size should not exceed a third of the compacted depth, thus avoiding point loading onto the FLP Builder. Don’t forget single-size rounded stone will not compact but move around under traffic and be displaced.


2. Depth of aggregate and sand required

You will need about 15 to 23 cm (6 to 9”) of compacted aggregate to support a surface for light vehicles; while for pedestrian use, a compacted aggregate depth of 10 to 15 cm
(4 to 6”) should be enough.

Depth of sand bedding layer under paved areas should be about 4 to 5 cm (1.5 to 2”).

3. How to prepare the ground

First clear the area of any large stones or other objects which would damage the FLP Builder during installation. Level the area by removing any undulations and fill any ruts.
Grass can be left undisturbed but treat any persistent weeds such as thistles and docks with a strong, lasting weedkiller, such as sodium chlorate.

4. Laying the FLP Builder

Keep the FLP Builder wrapped against exposure to sunlight until you use it; then lay the
FLP Builder directly on top of the levelled ground, weighting the edges if windy.

5. Cutting and joining

You can easily cut FLP Builder to shape with a sharp knife, and you can span any required area by overlapping FLP Builder by 30 cm (12”).

6. Putting down the aggregate

FLP Builder is very strong, and will not be damaged by laying and compacting the aggregate provided you go about this sensibly. Dump the aggregate and push it forward onto the FLP Builder to the required depth allowing for compaction. Try to avoid running machinery over the FLP Builder until it is covered with the required depth of material. Do not traffic the area until the stone has been adequately compacted. Just simple, sensible precautions.

7. Compacting the aggregate

Compaction should be thorough enough to provide a solid, stable surface. Equipment selection will be dependant on the area being treated and the depth of the aggregate being laid.






For Drainage:

You can use graded or single-size clean stone as fill material with FLP Builder.

1. After you have dug your drainage trench; spread FLP Builder over it, and
weight it down temporarily if necessary.

2. Then gradually tip the first layer of fill onto the FLP Builder so that the fabric will line the trench. Do this carefully to avoid tearing the FLP Builder.


3. Now fill the trench almost to the top with aggregate, and wrap the FLP Builder over it - without leaving a double thickness on top.

If this is a ground-water drain, you can add topsoil to the level of the surrounds and seed with grass.

If the drain has to cope with surface water as well as ground water cover the FLP Builder with at least 150 mm of pea gravel – which should stay exposed, and will need occasional maintenance.

4. FLP Builder will achieve maximum permeability only after several days in its wet environment. Some types of soil are particularly difficult to filter – so do obtain specialist advice if you have doubts about your site.


Important Note:

The manner in which FLP Builder is installed, the aggregate used and the ground conditions involved can all affect the performance of FLP Builder and the success of your particular project.

If you are not experienced in carrying out the projects of the type listed in this information, you should seek advice from someone appropriately qualified. This information is a general guide only and therefore cannot cover all aspects involved.
