Long interlocking concrete block wall with a return, built on site

Yorkshire manufacture. Nationwide delivery.

You don’t need a block supplier. You need the job sorted.

We make the interlocking concrete blocks, move them to your site and lift them into place to form your bays, walls or barriers. One team handles supply, delivery and placement, with construction-led oversight of our works.

Start with the outcome

What do you need to build?

You don’t need to know block quantities or lifting methods. Tell us what the site has to do and we’ll work out the rest.

Waste & recycling bays

Segregate streams and keep the yard organised.

Aggregate & storage bays

Store stone, sand, soils and materials in clean, defined bays.

Dividing & segregation walls

Separate areas, materials and operations quickly.

Barriers & perimeters

Heavy, solid lines for site security and traffic control.

Blocks only

Delivered to your site, offloaded or placed, for your own team to build.

Something else, or not sure

Describe the problem. We’ll advise on the best approach.

How we deliver

One team. One contract.
From plan to placement.

Most customers end up juggling a block supplier, a haulier and a lifting firm. We handle all three, so there is one point of contact and one team accountable for getting the blocks made, delivered and placed.

  1. 01

    Plan it

    We look at the site, the access and what the structure has to do. On managed projects, once you’ve instructed us, we produce a layout and 3D visual so you can see the job before anything arrives.

    3D visuals show the proposed layout. Retaining walls and bays holding high stockpiles must be placed to an engineered design, provided by you or your engineer.

  2. Row of steel moulds used to cast interlocking concrete blocks

    Make it

    We cast our own interlocking blocks in three sizes, each with a cast-in lifting point and interlocking top profile.

  3. Flatbed trailer loaded with interlocking concrete blocks, strapped and ready to leave the yard
    03

    Move it

    Loaded, secured and delivered from Yorkshire to sites across the country, with the vehicle and lifting method chosen to suit your site.

  4. Telehandler with a lifting hook in front of interlocking blocks stacked on site

    Build it

    Blocks are lifted into position and assembled to the agreed layout, on ground you’ve prepared. You get a finished bay or wall, not a pile of blocks at the gate.

Plan it, in practice

From a sketch on a plan
to a layout you can walk around.

An example from a managed project. A waste transfer station needed its bays reorganised. The client marked up their site plan by hand. We turned it into a scaled layout drawing, then a 3D model they could explore before a single block was lifted.

  1. Client's hand-marked site plan with coloured lines showing where block walls were wanted
    01

    What the client gave us

    A marked-up site plan showing roughly where the walls should go.

  2. Scaled layout drawing showing interlocking block wall positions on the structural grid

    Our layout drawing

    Every wall set out to scale on the building grid, ready to agree and price.

  3. 3D model of the warehouse showing the interlocking block bays with waste stored in each bay

    The 3D model

    The finished layout in 3D, with bays, vehicles and access, so everyone can see it before we start.

Spin it round, zoom in and switch layers on and off.

Construction and logistics leadership

Your project isn’t handed to a salesman.

Chartered construction professional MCIOB, CMgr MCMI. Site assessment, buildability, compliance and delivery.
Experienced logistics specialist Industry-proven in transport, HIAB and heavy offloading.

Construction expertise meets delivery expertise. SS Block Wizard is run by a chartered construction professional and an experienced logistics specialist, and we manage every project from enquiry through to final placement.

Every managed project is reviewed through both lenses before it goes to site: construction, compliance and buildability on one side; transport, access, lifting and placement on the other.

  • Site assessmentAccess, ground and constraints understood before anything is ordered.
  • BuildabilityLayouts that work on your site, with your plant and your operations.
  • Sequencing and coordinationManufacture, vehicles, lifting and placement planned in the right order.
  • One point of responsibilityOne contact from first enquiry to final placement. No chasing three firms.

Flatbed, HIAB or telehandler

We don’t just drop them at the gate.

Every site is different. If you can offload yourself, we deliver on a flatbed. If you can’t, we send a HIAB or get a telehandler to site. Tight access, soft ground, overhead lines or long reach all change the right way to lift, so we pick the method that suits your site instead of forcing one approach.

  • Nationwide delivery coordinated from Yorkshire
  • HIAB or telehandler where that’s the right solution
  • Placement and assembly to your layout
  • Lift coordination handled by us

Engineered structures

Retaining wall or high bays? Bring your design.

Retaining walls, bays holding high stockpiles and more complex layouts need an engineered design. Send us your engineer’s design and we’ll price the blocks, delivery and placement against it. We don’t design structures, prepare ground, backfill or carry out groundworks.

  1. 01
    Your design

    Your structural engineer’s design or specification for the structure.

  2. 02
    Priced to the design

    We work out the blocks, delivery and lifting from it.

  3. 03
    Placed to the design

    We manufacture, deliver, lift and place the blocks as designed.

FAQs

Common questions.

Do you deliver outside Yorkshire?

Yes. We manufacture in Yorkshire and deliver nationwide where required.

Can I just buy the blocks?

Yes. There is no minimum order. We deliver on a flatbed if you can offload, or bring a HIAB or telehandler if you can’t. We can also place the blocks in position or assemble them to your layout.

Do you do groundworks, backfilling or building work?

No. We supply, deliver and place interlocking concrete blocks. Ground preparation, drainage, backfilling and any other building work are for you or your contractor, and we’re happy to work alongside them.

Do you use a HIAB or a telehandler?

Whatever the site needs. If you can offload yourself, we deliver on a flatbed. If you can’t, we send a HIAB or get a telehandler to site, chosen to suit your access and ground conditions.

Is a 3D visual an engineered design?

No. Our 3D visuals show the proposed layout so everyone is clear on what is being built. Where a structure needs an engineered design, for example a retaining wall or a bay holding high stockpiles, we price and place the blocks to your engineer’s design. We don’t provide structural design.

Do you do domestic jobs as well as commercial?

Yes. We work on commercial, industrial, agricultural and domestic sites, and every job is delivered to the same standard.

How much are the blocks?

It depends on the block size and the concrete mix. For example, our 1200 × 600 × 600mm block is £102 + VAT in RC35 and £104 + VAT in C40. The full price list is in the Buy blocks section. Delivery is quoted separately based on postcode, and HIAB or telehandler offloading and placement can be arranged where required.

What sizes are the blocks?

Our 600 range is 600 × 600 × 600mm, 1200 × 600 × 600mm and 1800 × 600 × 600mm, weighing approximately 0.6, 0.98 and 1.6 tonnes. Our 800 range is 800 × 800 × 800mm and 1600 × 800 × 800mm.
