Dexpan Expanding Grout
Вставка
- Опубліковано 24 сер 2024
- Dexpan expanding grout is used to remove a large boulder beside a dock. Some of the holes were underwater, so we made filling tubes from golf club protector sleeves. We checked the seal by blowing into the sleeves once they were jammed into the holes. You need a very good seal, no bubbles. This Dexpan is amazing stuff!
Excellent information, thanks for taking the time to make this video and share it!
So beautiful
Wow 👍👍👍
I just got my Dexpan delivered to me yesterday and I am wait for the hammer drill and 1 1/8th drill bit ordered from Ebay.
I live in NW Oregon then conduct guided Salmon & Steelhead fishing in small rivers with lots of boulders that are a pain to navigate around, and some are just dangerous to get a drift boat past.
Some of the boulders are getting cracked before summer and others are getting cracked then wiped out in the summer when the river water is at the lowest point.
I have 2 gas run generators so one is going in the boat to power the hammer drill.
Hi Lure, 1 1/8 holes should work fine, mine were 1 1/4 inch. On my second job (April 2021 UA-cam) I used an electric hammer drill and it took about six hours of drillling. The BIG thing is to keep the end of the bit wet. I used a small 120 volt utility pump, you only need a trickle of water. We did the first two holes dry and dulled the bit, then we did 25 holes wet and the bit was still sharp. Good luck! -Chris
@@MargotChris I know of so many places in the rivers here I would like to see a change in river steps to rocks I hate in the way to get around in the boat.
Some places are just sandstone to drill, and others are boulders I am going to crack then get rid of.
The first is a big sandstone rock on a rough road leading to the river I use for a boat launch with this rock snags my trailer axle.
All I really need is the top of the rock to be level with the ground, so the trailer axle passes by it.
I have a petrol hammer drill, much safer than electric where there is water. Can use SDS MAX drill bit upto about 1.5" diameter, or steels,etc.
@@stuartandrews4344 And where in the water I'm going to get to the gas generator and drill when it is in a Hugh 30-foot jet boat I am and standing in the jet boat by the rocks being drilled.
I'm not a ding bat in a leaky rowboat behaving like one of the 3 stooges.
From age 6 grandfather starter me operating a 20 foot Bar tender Ocean boat and I build my boats and have earned the time to qualify for the 25 ton USCG ship capton license which I have in my possession.
Amazing and very interesting video🎥.. Great information and very helpful.
Do keep posting
Warm regards and best wishes

Aren’t those golf club sleeve diameters like 1.25”? Isn’t the hole supposed to be 1.5”?
Very astute, Tripp. Yes, they are 1.25" holes, and they seemed to work just fine. Their website says 1 to 2.5 inches. I personally would avoid the 2.5 inches, my buddy had big holes (perhaps 3 inch) and his blew out like a geyser without splitting the rock.
Nice. You used a rotary hammer to drill the holes?
My brother had a commercial pneumatic rock drill. An electric rotary hammer drill would work but slower, I think. I would then go with slightly smaller bit to speed things up, not sure how small you can go and still get it to work.
Did you try to just split a rock in half? Making a line of holes? Just curious of the minimum amount of drilling to split a few rocks and time to do it with a electric rental drill.
@@btwiitchell55 You can see the number of holes at about 8 seconds into the video: lots! But with an electric drill, doing a line down the center and splitting the rock in half might be an idea. I've done some electric drilling, I always kept a small flow of water on the bit. Not sure how much slower it would have been doing electric.
I don't think I'd be happy using an electric drill while standing in the water... Air drill is the better option.
And what was the purpose of this?
OBVIOUSLY A WOMAN HERE

Wow
The rock was so sad that it just sunk to the bottom of the lake.
All the time drilling them holes with a powered rotary hammer when you could have used a stone chisel in it and done the same thing, good time and money waster though if that was your goal!
A stone chisel for slate might be a good idea, but for a 4 foot granite boulder? I don't think so. We did try "feathers and wedges" in the drilled holes initially, but it only broke out the top 8 inches of rock. Whereas the Dexpan split the rock right through.
@@MargotChris stone masons have done it for thousands of years before Dexpan was a thought. Everyone looks for a easy button instead of knowledge about the task at hand...
@@carolrobinson7779 Chisels on granite with no drilling? My understanding is that for splitting granite years ago, they would drill the hole with "star drills" that they would repeatedly hit with a hammer, then use feathers and wedges to do the actual split after hours of pounding. Perhaps you could share a video or pictures on your channel of granite splitting with just a chisel? I am interested.
@@MargotChris where did I say hand hammering? You obviously used a rotary hammer drill to drill the holes, they have bladed stone chisels for them like a jackhammer, I have several. Personally I would have drilled a series of deep closely spaced smaller 3/8" holes across the center first then switched to the chisel connecting the holes from one side to the other to form a breakline then smacked it with a sledge. Usually breaks the first whack. Masons work with straight lines not circles like it appears you did.
@@carolrobinson7779 Were you going to post a video of yours on how to do this or how you did it as a stone mason or just criticize this guy for spending a few hours breaking a granite Boulder?
