Cement Blocks (37)

Build a solid structure with cement blocks from Rona. These blocks are a reliable construction material for many projects, including outbuildings and retaining walls. They’re available in standard, uniform sizes to ensure stability, and offer the advantage of being low maintenance and durable.

Use landscaping blocks along with patio stones and pavers, and create a surface that stands up to heavy foot traffic, and the elements. Choose standard blocks with varying thickness, or deck post support blocks.
For all landscaping needs, cement blocks are available in a wide variety of shapes, sizes, and styles of pre-cast cement blocks to meet all project requirements and suit any design aesthetic. Select specialised deck blocks for patio posts and supports, or pier blocks for ground-level walkways and decks. These often feature built-in notches designed to hold beams, joists, and posts, while others include holes to accommodate concrete bolts for added support.

Use cement landscaping blocks to construct sturdy retaining walls that help protect against erosion and increase useful yard space. Made with two or three voids, blocks allow for steel rod inserts or concrete filling to reinforce the strength and durability. They also resist damage from insects and pests, increasing the lifespan of the finished product. To further enhance the look of the outdoor space, browse the selection of landscape fabrics to prevent weed growth, retain moisture, and improve the root development of garden plants.

Choose heavy-duty cement blocks for use in the construction of schools, offices, homes, and industrial retaining walls. Besides strength and durability, units offer the added benefits of natural fire and water resistance, and long-term airtightness. They also provide noise dampening properties and moderate temperature control for added comfort with a range of options for insulation. Resistance to extreme weather conditions is important during winters, and the blocks stand up well to heavy snow falls and gusting winds. These blocks are suitable for use with most roofing systems and offer good load bearing capacities, even supporting additional floors in double-story buildings.

Lightweight units are versatile and cost-effective, making them an excellent choice for smaller projects around the home. Create solid outdoor seating areas and benches that last year-round, set up cosy fire pits for friends and family, or build unique planters for herbs and garden plants.
