The PolyShark is a custom pump skid system for installation of single-component polyurethane geotech resins. This world-class skid set up is essential for large scale seawall repair, soil stabilization, and void fill projects.

The PolyShark includes a gas-powered high-pressure injection pump, two hose reels, and flow meters.

Gas-Powered High-Pressure Injection Pump

A step up for projects that require greater power and output, this custom modified pump is our best-selling gas over hydraulic piston machine, favored by contractors who want to complete large application jobs in record time with high profit margins. The hydraulic ram fluid section is moved front and center in the configuration for easier maintenance and control.

High-Pressure Hose Reels with Stainless Steel Ball Bearings

High-pressure design guarantees durability when used with the high-pressure single-component pump. The construction is completely corrosion resistant and the stainless steel ball bearings, hardware, and manifolds are stronger than the aluminum parts on standard hose reels. The ball bearing-driven hose reels operate smoothly because they contain no bushings. (Bushings easily wear out.)

Flow Meters

Two high-pressure flow meters are capable of recording the exact amount of product pushed through the hoselines. This allows for precision material-use tracking.

How to Deal with Bound Slabs on a Concrete Leveling Job

Body - How to Deal with Bound Slabs on a Concrete Leveling Job

When two adjacent slabs are touching, there is a high likelihood of them being bound. This is definitely something to look out for on slab lifting jobs for a variety of reasons.

Bound Slab Basics

If you try to lift a slab that is bound to an adjacent slab, you could end up:

  • Lifting a part of the slab that you did not intend to lift.
  • Cracking the slab.
  • Lifting the adjacent slab unintentionally.
  • Wasting valuable extra material trying to lift a slab that is stuck.

Even if a seam between two slabs or a control joint (a joint meant to break when the slab is under pressure in order to prevent cracking) is already loose - it's still best to run a saw through it just to be sure before attempting to lift. A concrete saw blade is 1/8-inch wide. When you cut between slabs, you are giving them a 1/8-inch gap to ensure smooth movement.

Pros and Cons of Two Types of Concrete Saws

There are two types of concrete saws to choose from when stocking your arsenal of slab lifting gear. Here are the pros and cons of each…

Circular Saw

PROS

  • Fast cutting rate.
  • Low operating cost.
  • Easily sourced blades.

CONS

  • Requires overcuts (the blade typically extends 4 to 6 inches past the edge of the slab).
  • Requires a wide berth. Cannot cut up against edges of walls and structures.

Concrete Chainsaw

PROS

  • Doesn't require overcuts.
  • Can cut up against the edges of walls and structures.
  • Can cut up to 12 inches deep.

CONS

  • Has a high operating cost (chains and bars tend to be expensive).
  • Low cut footage per bar and chain compared to circular saw blade.
