10mm Ballast

10mm ballast is a mixture of Sharp Sand and 4/10mm shingle used in concrete production making levels and bedding.


USES

• Used in concrete production

• Bedding

20mm Ballast

A mixture of sharp sand and rough shingle 4/20mm. Not suitable for drainage due to high fines content. Widely used in industrial building but also in domestic applications such as fence posting and concrete paths.


USES

• To add cement with to make a concrete mix 

• Fence posting 

• Concrete paths

30/50mm Rail Ballast

This Network Rail approved rail ballast is a specialist bedding stone made from natural stone used for laying below railway sleepers.


Rail track ballast serves as a bed for rail tracks and provides drainage and strength for heavy loads carried by trains. Ballast is spread beneath the rail track. The track ballast forms the track bed that supports the rail track load and provides water drainage. 


Rail ballast aggregate is typically 30-50mm aggregate. Hard and tough stone is required for rail ballast. Resists the severe attrition in a railway trackbed environment. Track ballast is typically granite as its strength delivers natural durability although other aggregate types can satisfy the requirements for trackbed ballast.


To ensure safety and performance materials are quailty tested. Our rail ballast complies to Network Rail standards for resistance to fragmentation, attrition and wear, cleanliness, durability against freeze-thaw, resistance to freeze-thawing and durability including resistance to freeze thaw and is a CE marked product.


This material can be delivered bagged or by loose loads (tipper & grab lorries). 


We supply a range of aggregates to suit other projects on the railway, click here to see a list of our materials. 


USES

  • Commonly Rail Track Ballast is a product specially used for rail track sub bases.

Topsoil

This multi purpose topsoil is screened to 10mm making it easy to handle and ensuring it rakes out to a smooth, even tilth. Our soil is a nutrient-rich, highly fertile, organic loam, ideal for planting or for use under turf. As a general rule, each bulk bag can cover an area of 30m2 to around 1” deep. Please note this natural product is not sterilised. Certified to British Standard BS3882:2015.


USES

• Filling flower beds and large planters

Recycled Aggregates

As environmental practices demand innovative and sustainable alternatives to quarried materials, we recycle and produce materials from construction and demolition waste. All of our Aggregates are produced at our aggregate production facility in Hertfordshire, where our recycled materials are screened and washed ensuring high quality product. All of our Recycled Aggregated are WRAP approved. Examples of Recycled Aggregate we offer are detailed below, scroll and click on the headings below.

Type 1 Crushed Concrete

Type 1 crushed concrete is screened 0-40mm in size and is produced in accordance with the specification for Highway Works 803 (SHW 803). This is a recycled and sustainable option to MOT Type 1 aggregate. 


Type 1 has a lower fines percentage than scalpings and therefore a greater load bearing capability. It is the recommended material for highly trafficked areas such as highways, car parks, footpaths, driveways and hard standings.


USES

• Sub-base material for roads, drives, tracks, paths, trench fill, backfill, capping layers, oversite fills and foundations.

• Used as a general purpose hardcore. 

• Backfill material

6F5

Formally known as 6F2, this recycled material is screened 75mm down to dust. 6F5 is a recycled aggregate that is made up of crushed hardcore materials including crushed concrete. 


Produced from construction and demolition waste, this product offers a number of environmental benefits, making it a sustainable material.


Typically used for capping sub formations prior to laying Type 1 or Type 2 sub-base. 


USES

• Ideal for embankments 

• fill materials 

• capping 

• sub-base.

• used for paving solutions 

• for laying cable and ducting.

• Covering pipes / electric cables

• Sub-soil

Washed Ballast

A sustainable and cheap alternative to Primary Ballast. A mixture of recycled sharp sand and recycled shingle. Not suitable for drainage due to high fines content.

USES

• Backfill

• Land reinstatement 

• Landscaping

Tarmac Plainings

Road planings - otherwise known as tarmac planings, road scalpings or tarmac scalpings - are a by-product of road and path resurfacing, where a cold milling machine removes asphalt from the surface sub-base, ready to be recycled. Once removed and cooled, these tarmac planings are a hard-wearing and weather resistant recycled aggregate. 


An inexpensive and environmentally sound way to resurface hardstandings, including car parks, footpaths, farm tracks, yards and haul roads. Can also be used as a sub-base or void filling material however has a higher content of fines compared to Type 1.


USES

• Hard-wearing and weather resident, ideal for high traffic areas.

• Use our road scalpings to resurface car parks, footpaths, farm tracks, yards and haul roads.

• Not an attractive finish so not typically suited to use in domestic gardens or driveways, except as a sub-base.
