I have a problem I hope you can help me with.  I have a 50 gallon metal drum, sunk under my foundation w/ a sump pump in it to drain water from my basement should I get flooded.

the problem is that the drum (real old) has a hole, about the size of a quarter) in the bottom of it.

The drum being about 4' below grade and the foundation level w/ a pond has water seeping in through the hole constantly.

My problem,  how do I plug the hole which is in about a foot of water and a couple of inches of dirt/silt from seepage.

I cannot get down to the hole physically, but can reach it with a 4' extension pole.

all suggestions are welcome.

Hello and thank you for the speed of response to the letter.
I have a problem there is a leak around the swimming pool and instead of having a passageway around the swimming pool was the main contractor status
Sand around it, but there are a lot of water in the region, we search for the leak, but if we drive out of wet sand around the swimming pool to search for the leak - Is there a way to cure without out the sand outside the swimming pool

Hi, i just received your DIY kit and there were no instructions with the kit which is really not a problem at all. I watched your videos a few times and am pretty confident at performing the job but the part that i need some help with is the mixing ratio. In the video it shows the worker pouring the grout into a cup then adding the activator which looked like 40mls. Is that 40mls added to a 1cup of grout? Does the manual grease gun only hold about 1cup of grout material?

We can't develop high pressures when needed with surface mount ports. It is also possible for the resin to travel just below the surface patching compound and not fully move into place before it creams.

why don't you guys use the wall mounted port method??

Most commercial jobs that have been specified by a consultant require the injection technician or the company doing the injection to have at least 5 years experience. Residential and any other jobs not run by a consultant don't request it. However, not being trained is a potential nightmare for you and building owners.

Johnson Group Online Inc. will be offering monthly training seminars on two topics:

Topic #1 is Injection Grouting for cracks in concrete structures and the business of grouting. (One Day)
This is geared toward small new contractors getting into residential or small commercial injection work. It will outline the technical basics of injection grouting with polyurethane and epoxy grouts using the methods we have for to be the best plus all of our tricks.
The business portion will outline best practices in sales, contract writing, who not to work for, pitfalls to avoid and the economics related to actually making money in the business.

Topic #2 is Interior Weeping Tile Systems and the business of offering that service. (One Day)
We have developed a great deal of expertise in this area and find it goes hand in hand with injection grouting. This course in also technical and theoretical in nature. There are site visits with both courses.

We will be accepting registration for these programs very shortly, and they should begin to run in May 2009 at our offices in Barrie, ON Canada. USA participants are very welcome to attend.

Pricing should be set up as follows:

One day, either course $750.00 CAD
Second day, $500 CAD
Per person.

More to be posted soon...
