We've blogged about this before, but it's worth repeating. Twin streaming is a technique in which you use a high pressure 3,000 psi F-valve to inject resin AND water at the same time. As you can see in the photo, the F-valve has two supply connections - one for water and one for resin. The water and resin come into contact before they exit the coupler.

Advantages:

1. Ensures there is enough water for the resin to react with.
2. Starts the reaction immediately.
3. Promotes faster reaction in cold water.

Filling Voids Above the Water Table

When working on jobs that require void filling behind walls, also known as curtain grouting, it is imperative that you are prepared for any obstacles that may occur. If the voids are large and dry, resin may not have enough water to react with when injected in the conventional manner. In this case injecting water behind the wall prior to injection might not be sufficient (especially if the void is open or filled with gravel, giving the water an easy path to escape). With twin streaming you are guaranteed there is enough water for the resin to fully react and fill the voids.

Injecting Resin Into Cold Water

Twin streaming also works well if you find yourself having to inject into a cold, underwater environment. You can inject warm water along with the resin to jump start the reaction process before the cold water gets a chance to slow down the process. The ratio of water to resin can be controlled by opening the valves at different angles. Some products such as Spetec PUR H100, Spetec PUR H200 and AP Fill 700 only need a little water to react with (10:1 resin to water is plenty). In this case, you would crack the water valve slightly, then open the resin valve all the way. Other products such as Spetec PUR GT500 and Spetec PUR GT350 need more water. A 2:1 or 1:1 ratio of resin to water both work well. In this case, you may want to open both valves all the way.

A large part of the market is still using old sprayfoam insulation guns to do heavy concrete lifting work. Let's take a look at some of the benefits of using a gun that's custom designed for slab lifting...

The Problem with Sprayfoam Insulation Guns Adapted for Slab Lifting

Don’t bring a knife to a gunfight! Sprayfoam insulation guns are made for the simple process of spraying foam at constant pressures. Slab lifting requires a gun that is designed to deal with changing pressures and back pressure without backing up or crossing over. Issues like leaky port connections, constant cleaning, and constant fumbling around with a clamp can drastically reduce production - adding a lot of man hours to each project. Not to mention long nights spent rebuilding and cleaning the gun after EVERY job. Did we mention that feeling in the pit of your stomach every time you have to call in yet another expensive replacement parts order? 

The Solution: A Gun Designed by Slab Lifting Experts for Slab Lifting Contractors

The MixMaster Pro was designed based on years of feedback from slab lifting contractors working in the field. Every known point of frustration and difficulty has been addressed in this sturdy, single-purpose gun. Further benefits include a lower cost of consumables (you can reuse ports with this gun), beefy check valves designed to handle the back pressure, and a short 10-minute breakdown/cleaning session at the end of each day. Not to mention the fact that this gun is a production BEAST - no leaky port connections, no fumbling with clamps. Watch your man hours on each project shrink accordingly. Did we mention you’ll have less replacement part orders? There are only a few inexpensive replacement parts on this gun - PERIOD.

(Today we feature a guest blog from our customer Randy Serhan, owner of JACC Structures in Saskatchewan.)

First of all, I'd like to thank Alchemy-Spetec for asking me to write a guest post on their blog.  If you're interested in polyurethane leak seal, I think you'll like this one.  I recently did a leak seal job for a homeowner up here in my Candian hometown of Nipawin, Saskatchewan.  He had water coming into his basement around a water line access sleeve.  It was leaking approximately 1/2 litre of water per minute.  He called me to see if I could resolve the issue.  I packed some oakum saturated with Spetec PUR GT500 into the sleeve around the water pipe.  The leak was stopped in under a minute.  I used a moderate quantity of the resin-saturated oakum to ensure the plug was approximately two inches deep.  It won't leak again.  The customer was extremely happy as this repair means he will no longer have to babysit the water pails all night.  He also has the peace of mind of knowing that this is a long lasting fix, so he doesn't have to re-visit the problem each spring or heavy rainfall.  When that leak shut down so fast, he look at me and said "that stuff is magic".

And now for the best part: click below to watch me shutting down that link in this video clip I took on the job!
