Single Concrete Pier System

 

Proper depth requirement can be reached by driving against the load of the structure.

 

• Site cleanliness and speed save time and minimize damage to landscape.

 

• Soil's load bearing capacities are tested by driving the pilings into the soil.

 

• Pre-cured/tested concrete allows immediate leveling of the structure.

 

• A safety factor is provided by load distribution and thixotrophy (decreased viscosity during stress)

Single Steel Pier System

 

• All the features of the Single Pro-Pier System.

 

• Rigid Steel connectors to help prevent horizontal movement during and

after installation.

 

• A longer, stronger warranty.

 

Double Concrete Pier System

 

• All the features of the Single Steel Pro-Pier System.

 

• A double wall pier system for twice the strength and twice the support.

 

• An unconditional lifetime transferable warranty

 

Single Drill Pier System

 

For homes and light commercial buildings, single drill concrete piers are concrete columns that are formed by drilling holes into the ground between 9- 12 feet deep and  pouring liquid concrete 3500 psi into holes and are reinforced with steel rebars that are tied together and lowered into the hole. Creating a perfect vertical shaft that is between 10-12 inches in diameter.

Pros

1. Can guarantee greater depth than pressed pilings.

2. Less lateral movement

3. Less structural stress

Cons

1. Waiting time of 5-7 days for concrete to cure after pouring.

2. Larger amounts of soil must be removed.

3. For Double Drill concrete piers pricing is higher.

Double Drill Pier System

 

For two story residential homes or heavier commercial buildings, double drill concrete piers are 8” in diameter formed by drilling two shafts  at a predetermined specified angle, this system works well at most areas because  the reversed v angle creates maximum upward support.

Pros

1. Can guarantee greater depth than pressed pilings.

2. Less lateral movement

3. Less structural stress

Cons

1. Waiting time of 5-7 days for concrete  to cure after pouring.

2. Larger amounts of soil must be removed.

3. For Double Drill concrete piers pricing is higher.

Type 9: Pier and Beam Foundation System

 

About Pier and Beam Foundations

 

Pier and beam construction was extremely popular in North Texas a century ago because of our clay soils and extremes in temperature, especially during the summer. Having a pier and beam foundation allowed the building to “move” with these extremes, without compromising the overall integrity of the structure.

 

Pier and beam construction utilizes a series of columns that support the weight of a beam, so the weight is distributed evenly across the entire base of the foundation. The pier may be made of wood, poured concrete, cement blocks, bricks or stone, and sits on a concrete foot either on the ground or below ground. The beam can be comprised of steel, wood or even concrete.

 

Over time, piers can deteriorate – especially ones made of wood -- and must be repaired or replaced. Since the beam holds the structure in place, repair or replacement must be carefully planned before starting.

 

Much of our business consists of pier and beam foundation work. One of our specialties is repairing historical homes that were built before 1930. We are one of the few companies that still install an in-ground site-cast steel reinforced concrete footing under pier and beam structures.

 

Many older homes have foundation systems that are not performing as designed. Some have bod art blocks or stumps, "stiff legs" which are a 4"X6" section of beam between the ground and the beam (very unstable as the soil sinks and swells) or have foundations that are too old and have failed.

 

Unlike slab repairs, each pier and beam repair is unique due to the varied ways they are constructed, so pricing is different on each job. Let us come out and give you a free inspection and give you a firm estimate of costs.

 

Type 10: Root Barrier System

 

WHAT IS A ROOT BARRIER?

Root barriers can be solid objects, sheets of material, zones of chemically treated soil

(typically, the chemicals come in the form of pellets that are attached to a fabric) or any

other barrier that keeps roots from growing into areas where they are not wanted.

 

WHAT TYPE OF ROOT BARRIER DOES FCS USE?

FCS installs root barriers made of a three layer plastic membrane. The second and

third layers give extra protection against penetration by root and make the membrane

tougher. By using a tough plastic membrane that is water proof, Foundation and Concrete

Services root barriers have the added benefit of acting as moisture barriers.

 

WHY USE A ROOT BARRIER TO PROTECT YOUR FOUNDATION?

When roots get under foundations they can cause damage by drying out soil and causing foundations to settle. Roots also break into pipes causing extensive plumbing damage. In this case broken pipes lead to saturated soils which will cause foundations to heave.

Stop the problem before it starts! Installing root barriers will be less expensive than foundation repairs. Just as brushing your teeth will not always prevent decay, root barriers will not prevent root problem, but they are an excellent measure of prevention.

HOW LONG DO ROOT BARRIERS LAST?

Root barriers made of concrete or plastic will last indefinitely. Chemical root

barriers have lives that range upwards of five years plus. The life of a chemical barrier is

strongly influenced by the amount of water that falls on and/or flows through the treated soil.

 

HOW ARE THEY INSTALLED?

Root barriers are installed by:

1. digging a trench,

2. laying the barrier material in the trench, and

3. refilling the trench.

For concrete barriers, the concrete is simply poured into the trench.

 

WHAT DO THEY COST?

Root barriers should be at least 3 feet deep. If they do not go at least one foot deeper than

the side of your foundation, they will do no good. For a standard 3 foot root barrier, the cost

is typically around $65.00 per foot with a $1,000 minimum. The cost may fluctuate, depending on the types of trees and how close the trees are to the barrier.

 

IS THERE A COST ADVANTAGE COMPARED TO FOUNDATION REPAIR?

Absolutely! The minimum price for foundation repairs is $2500. The average residential

foundation repair costs about $5,500. Root barriers are significant less expensive and less disruptive to install than typical foundation repairs.

Tunneling Services

 

WHAT ARE TUNNELS USED FOR?

Tunnels are used to gain access to the interior of your home, without having to break a

hole in your floor - much nicer! Generally, tunnels are dug to the length needed to reach under your home and measure 3 feet by 3 feet in cross section.

 

WHAT ARE THE ADVANTAGES OF TUNNELS?

Tunnels enable us to reach the parts of your foundation that are under the interior of your

home, without having to access it from inside of your home. Tunnels avoid the need to break holes through your slab, to tear out carpet, cut through wood or tile floors or otherwise damage the flooring in your home. When your home is lifted via tunnels you can stay in your home and do not need to remove furniture or move out.

 

WHAT HAPPENS TO TUNNELS UNDER MY HOME AFTER MY HOUSE IS LIFTED?

Generally, your tunnels are connected to a drainage system used to keep water from

accumulating under your home. In some cases, your tunnels will be connected to a gravity

drain, in others, to a sump pump. Tunnels should be left unfilled to facilitate any future plumbing repairs or foundation warranty work. After all, having gone through the expense of digging tunnels you might as well get full advantage of them.

 

WHAT HAPPENS IF THE TUNNELS COLLAPSE?

Tunnels are dug to allow pilings to be installed. Pilings are used to hold up your

foundation. Once pilings are installed your home is no longer sitting on the soil. Since the pilings are holding up your home it's of no consequence if the tunnel walls were to crumble.

 

HOW DO YOU DIG TUNNELS?

The old fashioned way - we dig your tunnels by hand! This is extremely difficult work, but is worth the effort!

 

WHAT DO TUNNELS COST?

Tunnels typically cost approximately $85.00 per foot to dig and drain.

French Drainage System

 

WHAT IS A FRENCH DRAIN?

French drains are trenches that contain a perforated drain pipe enveloped in gravel. Either the entire trench is lined with filter fabric, or the pipe is wrapped in filter fabric.

 

Generally, the trench is covered with grass.

 

WHEN DOES FCS RECOMMEND USING A FRENCH DRAIN?

French drains are designed to remove water that accumulates below the surface.

French drains are very good at collecting water accumulating in marshy or boggy

areas that have been created by over-watering or poor drainage.

 

HOW LONG DO FRENCH DRAINS LAST?

If the trench for a French drain is lined with filter cloth, the drain will last for many years. If

only the pipe is wrapped in filter cloth, soil will wash into the gravel in just a few years.

 

HOW DOES FCS INSTALLED THEM?

We start with digging a trench and grade it so the bottom is flat and evenly sloped. Next,

we line the trench with filter fabric. After the fabric is installed, 1 to 2 inches of gravel is

placed in the bottom of the trench. A perforated pipe is then laid on the gravel.

The trench is then filled 4 to 6 inches below the surface and the edges of the filter fabric

are laid over the top of the gravel. Finally, the top of the trench is filled with soil.

 

The French drains can either work with gravity, if enough of a slope is available, or

connected to sump pumps depending on your need.
