75 mm / 3″

Perfect for use on…

• Backfills
• Foundations

Special Granular Sub Base (SGSB) creates a solid gradable surface that is ready for topping with road crush. Common uses include sub bases of driveways and roads. Great for rough surfacing during construction phases, before finishing phases.

SGSB is blasted, crushed and screened to 3” minus with fines left in for optimal binding and compaction. For best results, compact after application. Compaction locks the product together like jigsaw pieces making the surface very stable.

Good for filling slightly muddy areas no more than 30 cm / 12” in depth. Areas deeper than 30 cm / 12” a coarser product should be considered, such as a 5” minus or larger. As well, if your site is very wet and muddy, we recommend the 5” minus and larger products instead of SGSB because they have better drainage.

This product is made from blue basalt.

125 mm / 5″

Perfect for use on…

• Back fills
• Elevation adjustments
• Road ballast
• Wet areas

Course Subgrade Crush (5” minus) with fines is excellent for creating weight bearing surfaces. As with the SGSB, the Course Subgrade Crush is still gradable and contains fines to create ideal binding and compaction. When compacted this product will lock together like puzzle pieces creating an incredibly strong sub base for your project.

Course Subgrade Crush is best suited for larger fills and wet areas. Often used in areas with poor drainage, in landscaping where elevation adjustments are needed, or where heavy weight bearing capacity is required such as logging roads.

Course Subgrade Crush has fewer steps to its production process, and we price it accordingly, making it an economical option.

Unsorted, approximately 300 mm / 12″ or less

Perfect for use on…

Road blasting

Large fills

Muddy areas

Unsorted blast rock is the perfect product for cost effectively filling large areas, creating an excellent weight bearing subsurface and traversing very wet areas.

Thickness of product application is what determines the weight bearing capacity. From trucks to high rises.

This product is used for function over beauty.

Size by Request, between 30cm / 1′ and 150 cm / 5′

Perfect for use on…

• Retaining walls
• Breakwaters & Marine environments
• Erosion Control

Rip Rap are large blasted rocks that are custom sorted to your size specification. Sizes vary from 1 to 5 feet in diameter. Rip Rap is angular and has excellent weight bearing, stacking and locking capabilities.

Made from Landtec’s blue basalt it is both beautiful and functional for making rock walls.

Other common uses for RIP rap include breakwaters, dock abutments, erosion control and stream rehabilitation.

Landtec Rip Rap has been independently tested and approved for use in aquatic/marine environments.

Please note that for safety, customers must be attended by an operator in the quarry at all times. Browsing near blasted faces can pose a risk to health and safety.

We do NOT accept…

• Products containing any plastic
• Products containing toxic substances
• Construction materials

We except some materials for tipping at our quarry site to be recycled. We charge a small fee for clean dirt and soil, and accept rock and gravel to be tipped free of charge.

All materials must be absolutely clean! Tipped materials may not include any plastic, garbage, concrete or contaminated materials. (Free from chemicals, fuels, oils, paints etc)

We strive in all ways to be conscientious stewards of the land and the community. Our quarry does not have the facilities to reprocess contaminated materials so we ask that those be taken to appropriate locations in town.

Advanced notice is required for this service. Please contact us for more information.

Constraints…

• Blast product base
• Minimum order requirements

Landtec has worked in partnership with government, ministry of transportation, and construction contractors to arrange bulk custom crushing of a variety of products.

We have a number of strategies to guarantee quality and consistency of the final product. We regularly test products during production if this is something that customers require.

With prepaid bulk orders, discount pricing can be negotiated on a case by case basis.

To avoid disappointment, please note that we currently crush all of our products on a 2 year schedule. If bulk crushing can help your project reach out as early as possible.
