Mechanical lock to new concrete 

Typical Uses 

Ameron T-Lock, on the market since 

1947 with well over 175,000,000 square 

feet (nearly 16,000,000 square meters) 

installed, is now entering a period of resurgence 

as design engineers all over the 

world are rediscovering its broad range 

of physical and chemical properties. 

Ameron T-Lock is often used to line tanks, 

sumps, neutralization basins, clarifiers, 

thickeners and other structures. Ameron 

T-Lock has long been recognized for the 

outstanding corrosion protection it provides 

in sewage treatment plants and as 

a liner for thousands of miles of concrete 

sewer pipe, along with large diameter 

concrete waste effluent piping in many 

different industrial facilities. 

For Steel and Certain 

Concrete Surfaces 

Ameron T-Lock-Plain Sheet is installed 

in existing tanks and structures, and 

also makes a superior membrane under 

acid-proof brick. Sheets are applied with 

Ameron T-Lock adhesive and joined together 

by fusing Ameron T-Lock welding 

strip over the joints with a hot air welding 

gun. This results in a continuous and 

highly impermeable membrane. 

For New Concrete Structures 

Where new concrete tanks are to be built, 

T-Lock Ameron T-Lock may be cast into 

the walls and made an integral part of 

the structure without the use of adhesive, 

thereby, providing a long-term mechanical 

lock, with hydrostatic back pressure 

resistance of 100 feet (30.5M) of head.

Typical 

Properties 

Thermoplastic—Ameron T-Lock remains 

flexible for handling and installation 

purposes throughout a normal working 

temperature range down to as low as 40°F 

(4°C). The average brittleness temperature 

per ASTM D746 test method is 5° F 

(-15°C). 

Welding—A continuous membrane is 

formed by heat fusing Ameron T-Lock 

weld strip over butted or lapped edges 

of the sheet. The same weld strip may be 

used to repair damage at any time during 

the life of the sheet. 

In-service temperature resistance 

in solutions—Withstands continuous 

immersion up to l50°F (66°C), although 

specific temperature limits depend upon 

the nature and concentration of the solution. 

Dielectric strength—Ameron T-Lock is 

a nonconductor of electricity and resists 

electrolysis. Dielectric strength of the 

sheet lining using ASTM Dl49 test method 

short time test is 500 volts per mil of 

thickness. 

Water absorption—Absorbs 0.1 to 0.4 

percent during the first 24 hours, then 

the rate drops rapidly using ASTM D149 

D570 test method. Total absorbed amount 

is not significantly increased during any 

prolonged period. 

Water vapor transmission—Using ASTM 

E96 test method, the transmission rate is 

less than 0.1 gram per l00 square inches 

in 24 hours at 77°F (25°C) and 23.5 mm of 

mercury. 

Gas transmission rate—Using 40-mil 

sheet and ASTM test method D1434 

Procedure V, the rate of transmission with 

a l6-inch water column pressure was 0.0 

cc/100 sq in./24 hours. At 3 atmospheres, 

the rate was l6.8 cc/100 sq in./24 hr 

average. Great care must be exercised in 

making the fusion welds and in repairing 

nail holes, snap-tie holes, etc., so that the 

installed system will pass a reasonable 

gas tightness test if required in certain 

applications.

Coefficient of thermal expansion—Using 

ASTM D696 test method, the coefficient 

is 0.0001 in./in./°F. T-Lock, when 

cast into concrete pipe or structures, 

does not expand or contract to any 

greater or lesser extent than the concrete. 

Plain Sheet moves with the steel 

substrate. 

Hardness—Shore Durometer “D” is 

approximately 54 at ambient temperature 

per ASTM D2240 test method. This 

equates to approximately 95 on the “A” 

scale. 

Tensile strength of parent material— 

2200 psi minimum per ASTM D412 test 

method. Factory welds are a minimum 

2000 psi test. 

Elongation of parent material—200 

percent minimum per ASTM D412 test 

method. 

Abrasion resistance—Using ASTM 

D1044 test method with a CS-17 

Calibrase Wheel loaded to 1000 g, the 

weight loss is 35 mg per 1000 cycles. 

This is substantially better than bare 

concrete or vitrified clay. 

Coefficient of friction—Using ASTM 

D1894 test method, the static coefficient 

is 0.75 and the kinetic coefficient 

is 0.54. 

Specific Gravity—Using ASTM D792 

test method, the specific gravity is 1.28. 

Tear Resistance—Using ASTM D1004 

test method, the tear resistance is 

220g/mil. 

Brittleness Temperature—Using ASTM 

D746 test method, the low brittleness 

temperature is 5°F. 

Volume Resistivity—Using ASTM D257 

test method, the value is 5.8 x 10 12 

OHM - CM. 

Surface Resistivity—Using ASTM D257 

test method, the value is 1.1 x 10 14 

OHMS. 

Pull-Out Resistance—100 pounds per 

lineal inch of Tee at 75°F (24°C) from 

cured concrete. 

Chemical 

Resistance 

Chart 

Acid resistance—Ameron T-Lock performs 

well in continuous exposure to 

most mineral acids. Ameron T-Lock is 

also resistant to immersion in specific 

organic acids. 

Salt resistance—Resistance to many 

highly corrosive salts, including sodium 

chloride, copper sulfate, calcium chloride 

and alum. 

Alkali resistance—Good resistance 

to alkalies. Withstands dilute caustic 

soda at ambient temperature. 

Solvent resistance—T-Lock resists 

dilute solutions of alcohols that normally 

occur in sewage wastes; it is not 

resistant to chlorinated hydrocarbons, 

esters, ketones and similar solvents. 

Petroleum resistance—T-Lock withstands 

exposure to petroleum products 

that normally occur in municipal waste 

disposal systems; it is not designed for 

continuous exposure to high concentrations 

of petroleum products. 

Vegetable and animal oil resistance— 

T-Lock resists repeated exposure to 

liquid vegetable and animal oils that 

occur as components of municipal or 

industrial wastes. 

Fungi and bacteria resistance—Continuous 

exposure to actions of fungi 

and bacteria have no effect since T- 

Lock provides no sustenance for such 

growths. 

Plating Solutions 

Plating tank operators must test 

Ameron T-Lock to determine its suitability 

and expected performance life 

for their particular mixtures, including 

proprietary additives and temperature 

range. Extra layers may be appropriate 

in some applications, especially at 

liquid/atmosphere interface and above. 

Chemical Testing 

Ameron T-Lock has been tested in 

continuous immersion of the following 

chemicals at the temperatures shown 

for a period of one year. It is the nature 

of this material that it may show discoloration 

in some solutions, and in some 

of the most severe applications, it may 

gradually begin to swell or harden. Such 

observations do not mean the lining 

system has failed, and if left alone, it 

may perform well for many years.
