BIG-FOOT® Polymer Slurry Freeze Protection

FreezingBIGFOOTSq.jpg

Construction drilling using slurry and cold weather don’t mix that well.  In the drilling industry when using slurry a number of things can go wrong when the temperature drops below 32°F.  The polymer slurry will freeze.  Taking a few simple precautions easily prevents damage and equipment failure due to expanding from freezing.

 

RV Anti-Freeze

Not recommended as the mix ratios for protection from freezing should be 20 to 1.  As extreme cold periods and wind chill temperatures decline the mix ratios can be even higher.  This equals 1000-1500-gallons required per a 19,000-gallon slurry tank to just slow the freezing.  Propylene Glycol is not a permanent anti-freeze.  It must be mixed into the water for the best results.  This is usually not possible as the slurry is actively being used.  It should only be used for inactive equipment where the water or slurry is not drained from the systems.  The propylene glycol can be applied onto the Kelly bar to keep it from freezing.  Propylene Glycol is red colored and is used for deicing airplanes. 


Temperature at 32°F Overnight

Be sure to install air lines within the slurry tanks to bubble the polymer slurry.  This keeps the slurry moving and is very effective at preventing the slurry from freezing.   Bubblers = 1-inch PVC placed into the tank with slots along the pipe and a closed end.  The PVC pipe is weighted down on the bottom of the tank using sections of rebar.  An air compressor is hooked into the 1-inch line.

Severe Freezing Temperatures and Wind Chill Protection 

A very effective method at preventing polymer slurry from freezing in extreme freezing temperatures within the Frac tanks is an innovative portable heat distribution system that circulates heated fluid through a series of hoses connected to the Thawzall heat zone TCH 250 unit.

Hoses & Valves 

The slurry supply lines, and valves can be wrapped with a PowerBlanket to heat with electricity and prevent freezing.  Powerblanket can be obtained from farm & Fleet or Northern Tool.  Briskheat is another source of thermostat controlled heat tape.

Build Enclosure Walls Around Slurry Tanks

Another option on projects is to fully enclose the slurry tanks with a wood and insulated walled structure made from 2x4 wood plywood and panels of insulation.  Portable gas heaters are then used within to maintain a warm temperature.

Portable Gas Heater

The use of portable gas heaters can be used to heat the covered valves and fittings on the ends of the slurry tanks.

Rumor has it BIG-FOOT was spotted numerous times throughout the week and there was even a report of him walking Bourbon Street late at night.

BIG-FOOT sightings have become more frequent, and through word-of-mouth and proof of excellence the popularity is growing. This was evident by the number of attendees that stopped by the MATRIX exhibit booth where COO, John Berry, was present to interact directly with clients.

MATRIX is proud to be a participant in the DFI Conference and we hope to see you all again next year. 

 

 

BIG-FOOT® Sighting Reported at the Geotechnical Conference in Hershey, PA Nov 4, 2015

At approximately 4pm on November 4, 2015 Attendees of the 28th Central Pennsylvania Geotechnical Conference were witness to another BIG-FOOT sighting.  The event, sponsored by ASCE was well attended by over 450 attendees and 35 exhibitors. John Berry, COO of MATRIX Construction Products presented an informational session entitled Polymer Slurry Drilling/Construction Drilling Applications. 

In order to gain full utilization of polymer drilling slurry additives it is necessary to become familiar with the types of polymers used to enhance drilling slurry properties. This knowledge allows the end-user to correctly apply a given polymer to meet a specific requirement of the drilling operation.

The objective of the informative session was to acquaint the participants with the proper use of BIG-FOOT® Polymer Slurry as applied to the installation of drilled shafts projects. In addition attendees were introduced to the function of polymer drilling slurry. Demonstrations and hands-on training were provided to demonstrate how MATRIX additives work and how easy BIG-FOOT is to mix. 

It is safe to say that even the biggest skeptic left the session a believer. BIG-FOOT is real and we have proof. Click here for more information about this event. 

BIG-FOOT® SHOWS at IFCEE IN SAN ANTONIO

IFCEE-San Antonio-Exhibit photo-3-23-15.jpg

The International Foundations Congress & Equipment Exposition (IFCEE) held at the JW Marriott San Antonio Hill Country Resort & Spa March 16-21, 2015 was a great show for MATRIX Construction Products, (MATRIX).  Over 150 exhibitors showcasing new products and technologies within the Foundation Industry attended the event along with more than 3000 attendees including Contractors, equipment manufacturers, Engineers, and university students.

This show was important to MATRIX as this provided an opportunity to display our products and services directly to our customer the Foundation Drilling contractor.  The response to MATRIX was overwhelming.  Many customers came by the exhibit booth to say that they would be switching to MATRIX from their current provider of polymer slurry.   On numerous occasions customers said that they had heard about BIG-FOOT® Polymer Slurry and how well the product performed.

One customer said they heard that the MATRIX formulas had improved all the drilling slurries, additives and chemicals currently available in the market so they gave it a shot. Adding, BIG-FOOT performed so exceptionally they had to cut back the amount they mixed because it yielded so well.

The IFCEE show was a big success for MATRIX.  The overall response from contractors expressing they were going to switch to BIG-FOOT demonstrated that the Foundation Drilling contractors are realizing the rumors are true...BIG-FOOT really DOES exist and outperforms the competition.

 

BIG-FOOT® Bridges the Gap

MATRIX was contacted by a foundation drilling contractor about a bridge project after their original slurry provider had been unsuccessful stabilizing the drilled shafts after 5-months.  MATRIX was asked to evaluate the Geology and site conditions and make a recommendation. 

 

BIG-FOOT® Polymer Slurry and M-Booster™ proved to be a winning combination

BIG-FOOT® Polymer Slurry and M-Booster™ proved to be a winning combination

The customer was in trouble and we were ready for the challenge.  MATRIX was given one week to mobilize personnel and equipment and ship product to perform a trial shaft on the beach within close proximity to where the other drilled shafts had failed. MATRIX seized this opportunity, addressed the challenges and succeeded.  

 

The intelligence MATRIX provided helped the drilling contractor recover from cost over-runs as a result of 5-months of poor performance and non-production.

 

MATRIX was called upon to demonstrate that our slurry methods and procedures could be successful and sound.  They were.  MATRIX also developed an engineered slurry to the Geology onsite and made the following adjustments and recommendations that resulted in successful operations, helping the contractor get back on track:

 

1.     Shortened top casing

2.     Stopped vibrating casing after drilling under slurry started.

3.     Adjusted tank circulation to remove dead spots.

4.     Improved mixing with proper mixer for proper yield of the polymer and additive.

5.     Engineered a slurry recipe based on the Geology.

6.     Used Pure 100% active ingredients Matrix products no blended (Smart) products.

7.     No caustic chemicals.  All products Matrix provides are safe to handle.

8.     Instituted the elevated Top casing to provide proper hydrostatic head pressure.

9.     Insisted on manning the drilled excavation 24-hr all-night to top off the slurry and prevent cave-in.  This resulted in no collapsed holes.

 

The geology always dictates.

 

The MATRIX solution resulted in less slurry used and improved cost savings. Applying engineered slurry to the site Geology with competent field support is what we do. Contact MATRIX to see what we can do to help with your next project.
